Description

Die Erfindung betrifft ein Schiff mit einer Vorrichtung zur Stabilisierung, mit einem aufblasbaren Auftriebskörper in Ballonform als Rettungseinrichtung, wobei zur Befüllung der Auftriebskörper Erzeuger von Gas mit komprimiert gespeicherten Gasen angeordnet sind.
Vorrichtungen dieser Art sind beispielsweise aus der DE 199 21 670 A1 , der DE 3 227 348 A1 und der DE 3 421 904 A1 als Auftriebshilfen bzw. Seenotrettungseinrichtungen auf der Basis von Druckgassystemen bekannt geworden. Üblicherweise werden hierbei Kaltgassysteme, basierend auf komprimiert gespeicherten Gasen, wie Stickstoff, Helium, Kohlendioxid, Druckluft oder dergleichen, verwendet, mit denen Auftriebskörper, die typischerweise eine Ballonform aufweisen, aufgeblasen werden. Der Einsatz solcher Auftriebshilfen ist allerdings insofern auf kleinere Schiffe beschränkt, als die zur Stabilisierung von großen Schiffen erforderliche Gasmenge aus Druckflaschen in der Regel nicht schnell erzeugbar ist. Anwendungen für Schiffe mit mehr als ca. 30 Meter Länge sind daher bislang nicht bekannt geworden. Problematisch bei einer Verwendung eines solchen Kaltgassystems kann außerdem die Abkühlung des Druckgases aufgrund seiner Expansion sein.The invention relates to a ship with a device for stabilization, with an inflatable buoyant body in the form of a balloon as a rescue device, being arranged to fill the buoyant body producers of gas with compressed stored gases.
Devices of this kind are for example from the DE 199 21 670 A1 , of the DE 3 227 348 A1 and the DE 3 421 904 A1 become known as buoyancy aids or rescue services on the basis of compressed gas systems. Typically, this cold gas systems, based on compressed stored gases, such as nitrogen, helium, carbon dioxide, compressed air or the like, are used with which buoyancy bodies, which typically have a balloon shape, are inflated. However, the use of such buoyancy aids is limited to smaller vessels insofar as the amount of gas required to stabilize large vessels from pressurized bottles can not generally be generated quickly. Applications for ships over 30 meters in length are therefore not yet known. The problem with using such a cold gas system may also be the cooling of the compressed gas due to its expansion.

Es sind bereits Anordnungen gemäß DE 39 00 572 C2 bekannt, die eine Verwendung von Gasgeneratoren der genannten Art im Zusammenhang mit Rettungssystemen für Unterwasserfahrzeuge und zur Bergung von Unterwasserkörpern mit Hilfe gasgefüllter Ballons aufweisen. Die zu diesem Zweck verwendeten Gasgeneratoren basieren in der Regel auf Triebwerkstechnologien aus der Raumfahrt und bestehen aus Gaserzeugungssystemen auf der Basis der katalytischen Zersetzung eines flüssigen Energieträgers, vorzugsweise Hydrazin oder der Verbrennung von Feststoffen. Daneben sind aber auch Systeme bekannt geworden, bei denen das Auftriebsgas durch die chemische Reaktion eines festen Energieträgers, beispielsweise Lithiumhydrid, mit dem umgebenden Seewasser erzeugt wird. Ein Problem bei derartigen Systemen ist, daß auf reaktiven Substanzen basierende Gasgeneratoren typischerweise Abgastemperaturen oberhalb von 1000 K und mehr aufweisen, was zu einer Beschädigung bzw. Zerstörung der als Auftriebskörper verwendeten Ballonhülle führen kann. Aus der US 3 222 230 A ist eine Vorrichtung für ein Schiff bekannt, wobei zur Befüllung der aufblasbaren Auftriebskörper Gas dadurch erzeugt wird, dass Flüssiggas in einem Speicher mit Heißgase aus einem Heißgaserzeuger kombiniert werden. Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art so auszubilden, daß sie in der Lage ist, auch große Auftriebskörper innerhalb möglichst kurzer Zeit mit Druckgas zu füllen.There are already arrangements according to DE 39 00 572 C2 known to have a use of gas generators of the type mentioned in connection with rescue systems for underwater vehicles and for the recovery of underwater bodies using gas-filled balloons. The gas generators used for this purpose are usually based on aerospace engine technologies and consist of gas generating systems based on the catalytic decomposition of a liquid energy carrier, preferably hydrazine or the combustion of solids. In addition, however, systems have become known in which the lift gas is generated by the chemical reaction of a solid energy carrier, such as lithium hydride, with the surrounding seawater. A problem with such systems is that reactive substance based gas generators typically have exhaust gas temperatures above 1000 K and more, which can lead to damage or destruction of the balloon envelope used as the buoyant body. From the US 3 222 230 A a device for a ship is known, wherein for filling the inflatable buoyancy gas is generated by the fact that LPG are combined in a memory with hot gases from a hot gas generator. The object of the invention is therefore to provide a device of the type mentioned in such a way that it is able to fill even large buoyancy bodies within the shortest possible time with compressed gas.

Die Erfindung löst diese Aufgabe durch ein Schiff gemäß Anspruch 1. Durch die erfindunsgemäß vorgesehene kombinierte Verwendung von Heiß- und Kaltgas, bei der das Heißgas als Energiequelle genutzt wird, um eine rasche Expansion des Kaltgases zu ermöglichen, erlaubt das Füllen eines großen Auftriebskörpers und damit die Erzeugung eines großen Auftriebes innerhalb weniger Sekunden und ermöglicht so die Anwendung einer solchen Auftriebshilfe auch bei großen Schiffen und insbesondere bei Gefahrgutschiffen. Ferner ist die Vorrichtung erfindungsgemäß für eine Stabilisierung von Fähren und/oder Handelsschiffen und für das Heben von Schwerlasten vom Meeresgrund einsetzbar. Als Heißgasquelle können dabei alle in der Feststoff- oder Flüssigstoff-Raketentechnik verwendeten Mischungen Verwendung finden.The invention achieves this object by a ship according to claim 1. By erfindunsgemäß provided combined use of hot and cold gas, in which the hot gas is used as an energy source to allow rapid expansion of the cold gas, allows the filling of a large buoyant body and thus the generation of a large buoyancy within a few seconds, thus enabling the Application of such buoyancy aid even for large vessels and especially for dangerous goods ships. Furthermore, the device according to the invention for a stabilization of ferries and / or merchant ships and for the lifting of heavy loads from the seabed can be used. In this case, all mixtures used in solid rocket or liquid rocket technology can be used as hot gas source.

Der Vorteil der erfindunsgemäßen Vorrichtung liegt insbesondere darin, daß die Gastemperatur derart gewählt werden kann, daß einerseits das Material des Auftriebskörpers diese Gastemperatur noch ohne Beschädigung verträgt, daß andererseits die Gasraumtemperatur jedoch noch hoch genug ist, um große Gasvolumina in kürzester Zeit zu füllen. Auf diese Weise können mit der Vorrichtung erheblich schnellere Aufblaszeiten erzielt werden als dies mit einem reinen Druckgas-System möglich wäre.The advantage of the device according to the invention lies in the fact that the gas temperature can be chosen such that on the one hand the material of the buoyant body tolerates this gas temperature without damage, on the other hand, the gas chamber temperature is still high enough to fill large volumes of gas in no time. In this way, significantly faster inflation times can be achieved with the device than would be possible with a pure compressed gas system.

Die Vorrichtung nach der Erfindung basiert auf Technologien, wie sie prinzipiell von Raumfahrttriebwerken bekannt sind, und ist beispielsweise in der Lage, bei einem Einbauvolumen von nur ca. 0.25 Kubikmetern unter Atmosphärendruck innerhalb von 15 Sekunden ein Heißgasvolumen von 500 Kubikmetern zu erzeugen. Vorzugsweise ist ein Auftriebskörper insbesondere in Form eines Ballons an die Befüll-Leitung der erfindungsgemäßen Vorrichtung angeschlossen. Bei einer Aktivierung der erfindungsgemäßen Vorrichtung, beispielsweise durch ein elektrisches Aktivierungssignal, wird dieser Ballon zunächst innerhalb der ersten Sekunden nur mit Druckgas aufgeblasen, so daß sich zunächst ein Kaltgasvolumen zum Schutz der Ballonhülle bildet. Anschließend wird verzögert der Heißgas-Erzeuger aktiviert. Die Erfindung weist dabei den Vorteil auf, daß zum einen die Abgastemperatur so kontrolliert werden kann, daß die Ballonhülle keinen Schaden nimmt, zum anderen wird die Entleerungszeit und damit die Betriebsdauer einer Druckgasflasche mit einem integrierten Gasgenerator gemäß der Erfindung im Vergleich zu einer Druckgasflasche ohne einen derartigen Gasgenerator deutlich verbessert.The device according to the invention is based on technologies, as they are known in principle from aerospace engines, and is for example able to produce a hot gas volume of 500 cubic meters within 15 seconds with an installation volume of only about 0.25 cubic meters under atmospheric pressure. Preferably, a buoyant body is connected in particular in the form of a balloon to the filling line of the device according to the invention. Upon activation of the device according to the invention, for example by an electrical activation signal, this balloon is first inflated within the first seconds only with compressed gas, so that initially a cold gas volume is formed to protect the balloon envelope. Subsequently, the hot gas generator is delayed activated. The invention has the advantage that on the one hand, the exhaust gas temperature so can be controlled that the balloon envelope takes no harm, on the other hand, the emptying time and thus the service life of a compressed gas cylinder with an integrated gas generator according to the invention compared to a compressed gas cylinder without such a gas generator significantly improved.

Im Rahmen der Erfindung sind unterschiedliche Kombinationen von Heißgas- und Kaltgasquellen möglich. Auf diese Weise können Kaltgas- und Heißgas-Anteile so miteinander gemischt werden, daß sie mit einer vorgebbaren Mischungstemperatur in die Ballonhülle einströmen. Sollte es dennoch bei einem Heißgas-Erzeuger auf der Basis von Feststoffen zu einem unkontrollierten Abbrand und damit zu unzulässig hohen Drücken kommen, so würde eine in weiterer Ausgestaltung der erfindungsgemäßen Vorrichtung vorgesehene Überdrucksicherung für die Sicherheit der Anordnung sorgen.In the context of the invention, different combinations of hot gas and cold gas sources are possible. In this way, cold gas and hot gas portions can be mixed with each other so that they flow with a predetermined mixing temperature in the balloon envelope. If, however, in the case of a hot gas generator based on solids, uncontrolled burnup and hence inadmissibly high pressures occur, an overpressure safety device provided in a further embodiment of the device according to the invention would ensure the safety of the arrangement.

Vorteilhafte Ausbildungen der Erfindung sind durch die Merkmale der Unteransprüche gekennzeichnet.Advantageous embodiments of the invention are characterized by the features of the subclaims.

Die mit der Vorrichtung gemäß der Erfindung gefüllten Auftriebskörper können im Bedarfsfall durch die Erzeugung von zusätzlichem Auftrieb die Stabilität eines Schiffes aufrecht erhalten und so einer Krängung bzw. einer Schlagseite des Schiffes entgegenwirken. Die Erfindung kann dabei in unterschiedlichen Szenarien eingesetzt werden, unter anderem auch als präventive Installation an entsprechender Stelle an Bord eines Schiffes, in Form einer Zusatzausrüstung für Schiffe der Küstenwache bzw. an Bord von Spezialschiffen für die Bergung und Seenotrettung, aber auch in Form einer Spezialausrüstung für das Heben von Wracks. Die Auftriebskörper können im Fall kleinerer Fischerboote innerhalb von ca. 20 Sekunden, im Fall größerer Schiffe, wie großer Tankschiffe, innerhalb von ca. 60 Sekunden aufgeblasen werden. Die benötigten Gasvolumina liegen dabei zwischen etwa 20 und mehreren 100 Kubikmetern.If necessary, the buoyancy bodies filled with the device according to the invention can maintain the stability of a ship by generating additional buoyancy and thus counteract a heeling or an impact side of the ship. The invention can be used in different scenarios, including as a preventive installation at the appropriate point aboard a ship, in the form of additional equipment for ships of the Coast Guard or on board special ships for salvage and rescue, but also in the form of special equipment for lifting wrecks. The buoyancy can in the case of smaller fishing boats within about 20 seconds, in the case larger vessels, such as large tankers, are inflated within about 60 seconds. The required gas volumes are between about 20 and several 100 cubic meters.

Bei der in Fig. 1 schematisch dargestellten Anordnung sind zur Befüllung eines Auftriebskörpers in Form eines aus einem Polymer bestehenden Ballons ein Druckgas-Speicher 1 und in diesem ein Heißgas-Erzeuger 2 vorgesehen. Der Heißgas-Erzeuger 2 besteht aus einem pyrotechnischen Satz, der als Festtreibstoff-Kartusche in einem Gehäuse 3 angeordnet ist, das seinerseits über eine Halterung 4 im Inneren des Druckgas-Speichers 1 befestigt ist. Der Druckgas-Speicher 1 ist über eine Befüll-Leitung 5 mit einem Entnahmeventil 6 mit dem in der Figur nicht dargestellten Auftriebskörper verbunden, wobei in das Leitungssystem ferner eine Überdruck-Sicherung 7 integriert ist.At the in Fig. 1 schematically shown arrangement are for filling a buoyant body in the form of a balloon consisting of a polymer, a compressed gas storage 1 and in this a hot gas generator 2 is provided. The hot gas generator 2 consists of a pyrotechnic set, which is arranged as a solid fuel cartridge in a housing 3, which in turn is fastened via a holder 4 in the interior of the compressed gas storage 1. The pressurized gas reservoir 1 is connected via a filling line 5 with a removal valve 6 with the buoyancy body, not shown in the figure, wherein in the line system also an over-pressure fuse 7 is integrated.

Im Fall des hier beschriebenen Ausführungsbeispiels ist das Material des als Auftriebskörper dienenden Ballons bis zu einer maximalen Temperatur von ca. 230°C oder 500 K stabil. Bei einer ca. 5 mm starken Ballonhülle, die im eingetauchten Zustand vollständig von ca. 10°C warmem Seewasser umhüllt ist, darf eine maximale Gasraumtemperatur innerhalb des Ballons von 1000K nicht überschritten werden.In the case of the embodiment described here, the material of the balloon serving as a buoyant body is stable up to a maximum temperature of about 230 ° C or 500 K. With a balloon envelope of approx. 5 mm in diameter, which is completely surrounded by approx. 10 ° C warm seawater when submerged, a maximum gas chamber temperature within the balloon of 1000 K must not be exceeded.

Bei diesen Temperaturverhältnissen sorgt der Wärmeaustausch dafür, daß die Ballonhülle eine Temperatur von 500K innenseitig nicht überschreitet.At these temperature conditions, the heat exchange ensures that the balloon envelope does not exceed a temperature of 500K on the inside.

Der pyrotechnische Satz des Heißgas-Erzeugers 2 ist derart dimensioniert, daß bei einer Aktivierung der Anordnung, d.h., bei einem Öffnen des Entnahmeventils und dem Zünden des pyrotechnischen Satzes, die Abkühlung des Druckgases durch die Wärmeerzeugung des pyrotechnischen Satzes ausgeglichen wird, so daß eine Expansion bei konstanter Gastemperatur stattfinden kann. Da der pyrotechnische Satz nicht nur eine Wärme-, sondern auch eine Gasmassen-Quelle darstellt, kann der pyrotechnische Satz auch so dimensioniert werden, daß der Druck innerhalb des Druckgas-Speichers 1 entweder konstant bleibt oder aber sogar ansteigt.The pyrotechnic set of the hot gas generator 2 is dimensioned such that upon activation of the arrangement, ie, when opening the bleed valve and the ignition of the pyrotechnic charge, the cooling of the compressed gas is compensated by the heat generation of the pyrotechnic charge, so that an expansion can take place at constant gas temperature. Since the pyrotechnic composition is not only a source of heat, but also a source of gas mass, the pyrotechnic composition can also be dimensioned so that the pressure within the compressed-gas reservoir 1 either remains constant or even increases.

Bei der in Fig. 2 dargestellten alternativen Anordnung ist ein Heißgas-Erzeuger 12 vorgesehen, der in diesem Fall in einem Gehäuse 13 außerhalb Druckgas-Speichers 11 angeordnet ist. Bei dem Heißgas-Erzeuger 12 handelt es sich in diesem Fall um einen bereits aus der Raketentechnik bekannten Gasgenerator auf der Basis katalytisch zersetzbarer Stoffe, wobei alternativ auch eine Kombination von Feststoff und Flüssigstoff einsetzbar ist.At the in Fig. 2 illustrated alternative arrangement, a hot gas generator 12 is provided, which is arranged in this case in a housing 13 outside compressed gas storage 11. The hot-gas generator 12 is in this case an already known from the rocket technology gas generator based on catalytically decomposable substances, wherein alternatively, a combination of solid and liquid material is used.

Die Gase des Heißgas-Erzeugers 12 und das vom Druckgas-Speicher 12 gelieferte Kaltgas werden in einer Mischkammer 14 zusammengeführt, wo die gewünschte Abgastemperatur für den Auftriebskörper eingestellt wird. Der Druckgas-Speicher 11 ist bei dieser Anordnung über ein Entnahmeventil 16 mit der Mischkammer 14 verbunden. Auch bei dieser Anordnung ist in das Leitungssystem der Befüll-Leitung 15 eine Überdruck-Sicherung 17 integriert.The gases of the hot gas generator 12 and the cold gas supplied from the compressed gas reservoir 12 are combined in a mixing chamber 14, where the desired exhaust gas temperature is set for the buoyant body. The compressed gas storage 11 is connected in this arrangement via a removal valve 16 with the mixing chamber 14. Also in this arrangement, an overpressure fuse 17 is integrated into the conduit system of the filling line 15.

Bei dem in Fig. 3 dargestellten dritten Ausführungsbeispiel ist schließlich ein Heißgas-Erzeuger 22 in das Gehäuse 23 einer Mischkammer integriert, wobei die Mischkammer als Durchströmungskanal in Form eines Rohr- oder Stern-Innenbrenners ausgebildet ist. Ein Druckgas-Speicher 21 ist über ein Entnahmeventil 26 mit der Mischkammer 23 verbunden, die wiederum über eine Befüll-Leitung 25 mit dem nicht dargestellten Auftriebskörper verbunden ist, wobei in das Leitungssystem auch in diesem Fall eine Überdruck-Sicherung 27 integriert ist.At the in Fig. 3 illustrated third embodiment, finally, a hot gas generator 22 is integrated into the housing 23 of a mixing chamber, wherein the mixing chamber is formed as a flow channel in the form of a tube or star internal burner. A pressurized gas reservoir 21 is connected via an extraction valve 26 with the mixing chamber 23, which in turn is connected via a filling line 25 with the buoyancy body, not shown, wherein in the line system in this case, an overpressure fuse 27 is integrated.

Der Heißgas-Erzeuger besteht bei dieser Anordnung aus einem pyrotechnischen Satz. Bei der Verwendung eines Druckgases mit oxidativen Eigenschaften kann anstelle eines pyrotechnischen Satzes auch ein Festbrennstoff Anwendung finden, was dem Prinzip der Hybrid-Raketentechnologie mit einem deutlich erhöhten Oxidatoranteil entsprechen würde.The hot gas generator consists in this arrangement of a pyrotechnic charge. When using a pressurized gas with oxidative properties, a solid fuel can be used instead of a pyrotechnic composition, which would correspond to the principle of hybrid rocket technology with a significantly increased oxidizer content.
